rarer HEATER FOR INTAKE-MANIFOLDS.

Specification of Letters Patent.

Patented June a, 192(1).

Application filed July 18, 1919. Serial No. 311,709.

To all whom it may concern:

Be it known that I, GEORGE C. SHINN, residing at Vancouver, in thecounty of Clarke and State of Washington, have invented new and usefulImprovements in Heaters for Intake-Manifolds, of which the following isa specification.

This invention comprehends the provision of means for initially heatingthe intake manifold of a gas engine to facilitate startthe motor as thefuel is heated prior a single length of material and utilized from meansemployed for associating the intake manifold with the exhaust manifold,for holding the ends of the material in a position to form the casing.

The nature and advantages of the invention will be better understoodwhen the following detail description is taken in connection with theaccompanying drawings, the

invention residing in the construction, combination and arrangement ofparts as claimed.

In the drawings forming part of this specification, like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of a casing constructed in accordance withthe invention, showing the same arranged upon the intake manifold.

' Fig. 2 is a vertical sectional view taken on line 2-2 of Fig; 1. i i

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a detail section taken on the line 4--4 of Fig. 1.

Fig.5 is a view of the blank from which the casing is formed.

Fig. 6 is a view of the torch.

Before entering into a detail description, of what is herein shown, Idesire to have it understood that the casing is formed from a singleblank of material, which may vary in shape and size for application toany make or design of motor.

In this specific embodiment of the invention an elongated blank ofmaterial is folded transversely at a point between the ends thereof toprovide the front and rear walls 10 and 11 respectively of the casing.As

shown in Fig. 5 the blank of material is formed with an extension 12projecting from one side of the material adjacent one end thereof. Inthe formation of the casing, this extension is carried by the rear wall11. and 1s adapted to be bent around the front wall 10 to form the onesidewall of the cas ng. This side wall terminates short of the lower endof the casing to define an open- 1ng orpassage 1 1 for that part of theintake manifold connected to the. carbureter. As shown in this instance,the opposite side of the casing is normally closed by means of a door15, also formed from a piece of metal and given a substantially U-shapedconfiguration in cross section. The parallel be swung to the positionillustrated in Fig. 1 when it is necessary to have access to the casing;p

Upon reference to Fig. 1 of the drawings 1t will be noted that-whenthedevice is in place the intake manifold is arranged between the frontand rear walls 10 and IL respectively, the casing being designed tocompletely envelop the intake manifold or substantially so. The frontwall 10 adjacent its upper end is curved as at 15 in the direction ofthe rear wall to accommodate the pipe A, while the free ends of thematerial from which the casing is formed are disposed in parallelism andin contacting engagement' to each other. These ends are then positionedbeneath the clamps D utilized for associating the intake manifold withthe exhaust manifold of the engine. In this manner, the ends of thematerial are maintained in proper position to form the casing. Inpractice, the door 15 is opened and arranged in the position disclosedin Fig. 1, to permit a torch 18 carried by one end of a wire rod 19 tobe positioned within the casing. The torch 18 is of course saturatedwith gasolene or the like, and after the torch has been ignited, thedoor 15 is swun to a closed position. Consequently, the intake manifoldis heated in short order by the flame of the torch, prior to startingthe motor, so that when it is desired to start the with a sleeve ofasbestos which surrounds motor, the intake manifold will be hot enoughto heat the fuel passing therethrough to facilitate starting of themotor. The torch burns out" in' a few minutes after which the elements19 are removed from the cas that portion of the intake manifold passingthrough said opening.

While I have shown and described What I consider the preferredembodiment of the invention, I desire to have it understood that I donot limit myself to the construction,

shown and described, inasmuch as such changes may be resorted to whendesired as fall within the scope of what is claimed.

Having thus described my invention what I claim as new is:

1 The combination with an intake manifold and an exhaust manifold of anengine, and means for securing said manifolds together, of a casingformed from a single blank of material and designed to envelopsaid'intake manifold, and the free ends of said material from which thecasing is formed being arranged in parallelism and held associated bysaid means utilized for securing said manifolds together.

2. A casing of the character described comprising a single blank ofmaterial folded between its ends to provide afront and rear wall of the,casing, and an extension projecting from, one side of the blankandfolded to provide one side wall of the casing, a door pivotallymounted upon the front and rear Walls and designed to embrace theopposite side edges of said walls, said front the straight wall andarranged to embrace the adjacent edge of each of the walls of saidheater,and a closure pivoted at its lower end and designed to embracethe opposite edges of said walls as described.

4. A heater of the character described comprising a length of materialbent into substantially U-shaped formation, one wall of the heater beingperfectly straight, the opposite wall being curved in the directionof'the straight wall and terminating to lie in parallelism with thestraight wall, contacting the latter, oppositely curved projectionsformed on one side of the heater and projecting from the respectivewalls thereof, an extension projecting from the straight wall anddesigned to embrace the adjacent edge of the other wall, a substantiallyU- shaped closure pivoted, on said heater and arranged toembrace theopposite edges of "the walls for the purpose specified.

In testimony whereof I afiix my signature.

GEORGE C. SHINN.
